This study aimed to examine gustducin immunoreactivities when adopting various immunostaining conditions in rat vallate taste buds. The occurrence and intensity of the immunoreactivities exhibited specific patterns in accordance with the fixation time. The immunoreactions were localized to only taste hairs, the upper part of the taste bud, after short fixation periods but then to the cell-body cytoplasm excluding the taste hairs after long fixation periods. These immunohistochemical data suggest that the staining protocols, especially the fixation time, cause discrepancies in gustducin immunoreactivities.
